This n8n workflow automates the process of converting a PDF document to PDF/A format, often used for archival purposes. Starting with a manual trigger (which can be replaced with other triggers), the workflow downloads a PDF file from a URL, converts it to PDF/A via an external API, and then saves the converted file to disk.
### Steps involved:
1. Manual trigger to initiate the workflow.
2. Download a sample PDF file from a remote URL via an HTTP request.
3. Send the downloaded PDF to an external API (ConvertAPI) for conversion to PDF/A format. This involves authentication with the API, and the request is set as a multipart-form-data POST request.
4. Save the resulting PDF/A file to disk.
### Practical use case:
This workflow is ideal for content management, archival, or compliance workflows where documents need to be stored in PDF/A format for long-term preservation or regulatory reasons. Automating this process reduces manual effort and ensures consistent formatting.
### Key features:
– External API integration for file conversion.
– Easy customization through API credentials.
– Automated file download and storage.
